WADER

Sonar Range Prediction and
Global Ocean Information System

What is WADER?

WADER is a comprehensive sonar range prediction and Global Ocean Information System which combines environmental data together with user-supplied parameters to generate propagation loss data (PL) and calculate sonar probability of detection.

Designed for users of all abilities, data is generated in real time.  Analysis of the data can provide information such as best evasion depth, likely target depths and optimum sonar position.

WADER is supplied with Sonar Parameters for Unclassified Training Systems (SPUTS), global bathymetry, environmental and sediment databases together with a wide variety of oceanographic reference chart types so that WADER has everything it required to perform sonar range predictions out of the box.  Users are able to upload their own sensor parameters, high-resolution bathymetry data and customisable chart overlays.

Main Screen

The Main Screen is the starting point for calculations where users define their area of interest and add detail to the map display. The Main Screen renders 2D sonar performance radial displays and provides access to the 3D Dynamic Area Display (3D DAD). In addition to the on-screen climatology data readouts, optional overlays include:
  • Sediment data charts
  • Ambient noise & weather data (with 3rd party product access)
  • Global port locations and ocean place names
  • User defined area boundaries

2D Radial Sonar Range Prediction

Distance Measuring Tool

WADER provides both flat plan and vertical slice propagation loss displays. The former are displayed on the Main Screen using colour coded ‘blobby radials’ which are plotted at 15 degree (or greater) intervals.

Each set of radials can be configured independently in terms of sonar type, frequency, depth and Figure of Merit (FOM).

This feature allows users to overlay distance markers on their chart, thus enabling the measurement of non detection zones and other features.

The distance markers can be toggled on and off.

3D Dynamic Area Display

The 3D Dynamic Area Display allows users to create an interactive 3D model of the seabed at any location.

This model can be augmented with a 3D rendering of Probability of Detection (PoD) from the surface to any depth down-to the seabed, maximum range circle and user-defined waypoints.

Multistatic Acoustics

Multistatic Grid Editor

WADER includes a number of predefined transducer patterns which can be augmented with user defined patterns.

The Multistatic Grid Editor has been updated to make the selection of different transducer patterns easier - this significantly improves the selection experience for tablet users.

The MSA is capable of predicting thousands of different transmitter/receiver position combinations via a 9x9 user-defined grid pattern (up to 81 transmitters and 81 receivers can be activated).

The angle of offset and spacing between the transducers can be easily adapted using the controls.

Environment Editor

The Environment Editor allows users to edit both the track and operational environment. Users can upload and manage their own (measured) environmental profiles (salinity & SSP) from XBTs using time filters, edit the seabed properties and analyse the sound channel. The data is visualised using the seabed cross section and profile viewers. High resolution water column profiles can be merged both manually or automatically with the track for use in the analysis screen.

Cross Section Viewer on the Environment Screen

WADER is range dependent and the cross section viewer enables the user to view the temperature, salinity, sound speed, potential density and buoyancy frequency along their chosen track.

Each set of radials can be configured independently in terms of sonar type, frequency, depth and Figure of Merit (FOM).

Profile ViewerAutomerge User ProfilesCross Section

DTSV Automerge

Users are able to upload their own profiles in DTSV onto both the WADER Main Screen and Environment Screen. These could be your own climatological datasets or bathy data of the day. Once uploaded, the user is able to automerge their own profiles with the climatology.

Each dot on the left hand chart represents a user's profile. In this case the profiles along the track have been auto-merged from 25km to the end of the track.

Users can also upload their own profiles within the Environment Screen in CPD, JJYY or JJVV format. Other formats may be incorporated; please contact OAD to discuss your requirements.

Profile ViewerAutomerge User ProfilesCross Section

Profile Viewer

The profile viewer enables the user to compare their own uploaded profiles with the embedded climatology (WOA 2018 and 2013). In the example to the right the user profile is red and the climatology is colour graduated.

WADER supports up to 102 points within a profile for higher fidelity.

Users can also display an Environmental Impact Assessment (EIA chart), best source depth and intensity distribution chart. In-situ adjustments can be made for ,amongst others, reverberation losses, target/source depths & sonar beam angle. Parameters for shipping, sea state and ambient noise are accounted for in the embedded Figure of Merit (FOM) calculators.

OAD WADER and HARCAM Annual Upgrade Plan

Batch Mode

WADER has been designed to conduct deep analysis of individual sensors, however there are times when it is helpful to compare the performance of multiple sensors within an environment, or different configurations of a single sensor.

Batch Mode has been developed to assist in this type of analysis by enabling users to pre-define a list of sensors and/or metrics. Once created, the user can use Batch Mode to process each sensor configuration for the environment and then toggle through the results to compare probabilities of detection.

Batch Mode

Range RingsCustom ContoursBatch ModeAnnual Upgrade Plan

Custom Contours

Users can highlight up to three contour depth lines, specifying the depth and colour of each. Areas shallower and/or deep than the contour can be flood-filled.
